Question

Distinguish between valency and atomicity ​

Answer 1

Answer:

VALENCY - This is the combining capacity of an atom.

ATOMICITY - The number of atoms present in molecule.

Answer 2

Answer:

Atomicity refers to Total number of atom present in a one molecule of an element. Valency refers to the no. of electrons present in an outermost shell of an element. ... = According to electronic configuration of Na(sodium), the valency is 1 because it have 1 electron in an outermost shell. Atomicity is defined as the total number of atoms that constitute a molecule. For example, each molecule of oxygen is composed of two oxygen atoms. So atomicity of oxygen is 2.In older contexts, the term atomicity is sometimes used in the same sense as valency while, Valency is the measure of the combining capacity of atoms or molecules. Therefore, it is the capacity of an atom of a single element to react and combine with particular numbers of atoms of another element.
